A rare case of coexistence of carcinoid tumor of appendix vermicularis and ileal endometriosis.

BACKGROUND

Carcinoid tumor is the most common tumor of appendix with overall good prognosis. Endometriosis is the implantation of endometrial glands and stroma outside the uterus.

CASE REPORT

We here report the coexistence of carcinoid tumor of appendix and ileal endometriosis in a 37-year-old nulliparous woman who came to the emergency room with right lower abdominal pain mimicking acute appendicitis. The main clinical and laboratory findings included fever, leukocytosis and elevated ESR. With preoperative suspicion of acute appendicitis, laparatomy was performed and revealed apparently normal looking appendix, along with a nodule in the terminal ileum. Both the appendix and ileal nodule were removed. Histological examinations revealed carcinoid tumor of appendix and ileal endometriosis. The case was discharged 4 days after surgery with no pain and symptoms and remained symptom free for the 1 year period of follow up.

CONCLUSION

Many cases of carcinoid tumor of the appendix and ileal endometriosis are diagnosed incidentally. Overall prognosis of these conditions is very good. Surgical treatment seems to be the best intervention for these disorders.
